This book examines Mark Twain's career in depth, tracing acts of plagiarism, false attributions, imposters posing as Twain or his associates, and the widespread piracy of his writing in countries without copyright enforcement. The study also highlights Twain's own allegations against other writers, his defenses of accused authors, and "visual plagiarisms" of images tied to his books, bringing to light how literary fraud both shaped and distorted Twain's legacy.
